Dectalk ISA model

[Debee Norling]

I still haven't gotten dtload to talk to my DecPC2. Has anyone tried it with
a PC2?

I'm now using CVS speakup and kernel 2.4.26. Speakup is happily talking to
serial synths.

I've tried using the firmware for my card, also tried using the firmware
that was bundled with this dec_pc.tgz that was on the speakup site.

I compiled the dtload source like this:
	gcc -O -o dtload dtload.c

the Readme says that the uppercase O flag is necessary for the I/O
instructions to work.

This Readme, which wasn't in the speakup documentation but was in the
Dec_pc.tgz on the speakup site also shows this usage:

>dtload [-v] [-t] [path]
>-v is verbose (gives all kinds of loading info )
>-t is test mode. takes what you type and says it.
>eof to quit the program in test mode.

The -v definitely is verbose. There are no errors; every firmware module
appears to load in to the card fine. It shows the address of where it is
loading and also some displays of registers.

However after all that, it exits with a status of -9 or -3.

And the -t test mode doesn't work. It never talks. Eof does exit without
crashing the first time; second time I try to use it in the current session,
it crashes. And not just that process hangs, the whole system hangs. I have
gotten to be real good friends with e2fsck and  where copies of my
superblock live ..

The Readme goes on to say:

>basic operation after the module is built and installed is:
>dtload
>echo decpc >/proc/speakup/synth

What module? Was I supposed to build this dtload as a module? How? You know
I'm not even sure this is the right Readme for this dtload. I need to find a
package where the Readme and source for sure match.

And changing the synthesizer simply crashes Speakup, no doubt because the
Dectalk isn't really "there" yet.

I'm eager to get this working because I want my serial port back.
